12 Claims. (Cl. 198-424) The present invention relates to a reciprocating barn gutter cleaner with an elevated delivery end wherein the operating parts are unitary and having a single power operating device.

An object of the present invention is to combine the gutter cleaner and elevator mechanism into a single unit so as to considerably reduce the initial cost and upkeep of the device. a

The present invention is an improvement over my issued patents, No. 2,467,988, issued April 19, 1949, and No. 2,593,340, issued April 15, 1952, wherein separate means must be provided for delivering the litter from the barn into a manure spreader or wheeled conveyor.

To these and other useful ends my invention consists of parts, combinations of parts, or their equivalents and mode of operation as hereinafter described and claimed,

and shown in the accompanying drawings in which,

Fig. 1 is a perspective view of a fraction of my invention.

Fig. 2. is a fractional top view of my invention.

Fig. 3 is a side view of the device as illustrated in Figure 2.

Fig. 4 is a sectional view taken on line 4-4 of Figure 2.

Fig. 5 is a sectional view taken on line 55 of Figure 1.

Fig. 6 is a top view of one of the chain links on which a scraper blade is pivoted.

Fig. 7 is a side elevational view of the link shown in Figure 6.

Fig. 8 is a front elevational view of a scuttle used for automatically controlling the opening in the wall of the building when the material is delivered to the exterior of the building.

Fig. 9 is a side elevational view of the scuttle as shown in Figure 8.

As thus illustrated the power and reciprocating means is designated in its entirety by reference character A. The barn gutter or barn trench is designated in its entirety by reference character B and the elevating extension trench to trench B is designated in its entirety by reference character C. p

The power and reciprocating means A is preferably similar to that shown in the above referred to Patent No. 2,467,988. Other means for oscillating the mechanism may be supplied. For example: that shown in Patent No. 2,593,340.

I have shown only a fraction of gutter B in Figures 2 and 3. This may be of any needed length and the driving connections may be positioned at the end of the device as shown or otherwise.

It will be understood that my device is operated intermittently at quite infrequent intervals and generally when it is convenient to provide, say a manure spreader for the reception of the material. Attention is now called to the fact that in conventional barn gutter cleaners the material is delivered from the end of the gutter which usually protrudes through the wall of the building, so the material Patented Sept. 6, 1960 vided with a separate power driving unit; whereas a novel feature of my invention is that there is a single power unit.

When applicants device extends through the wall of the building, a scuttle, which in its entirety is designated by reference character D is provided having means for automatically keeping the opening in the wall closed except for the passage of the material. Extension C to gutter B is secured to member D as shown having a curve E for an obvious purpose.

By observing Figures 1-3 it will be seen that the part of the gutter within the barn is straight for its length and that the extension C at its delivery end is in an elevated position for the purpose already recited.

Figure 4 illustrates fractionally gutter B, generally positioned within the barn, the side walls of which are designated by numerals 10 and 1 1 and the bottom being designated by numeral 12.

It will be noted that the trench or gutter within the barn is formed in the floor 9 of the barn and it may be of any necessary length. Power unit A may be positioned at the end of this trench as shown or in any other suitable position where it can be conveniently connected to a bar 13 by means of a pitman 14 having a suitable length and being rotatably connected at one end to endless chain 15 by means of a driving pin 16 connected to a link of chain 15 and at the other end to bar 13 as at 17 so the bar is oscillated a distance back and forth equal to the same travel of pin 16.

It will be seen that bar 13 (see Figure 3) may be any necessary length but it cannot extend into curve B. Therefore links F and G are necessary and clearly the links may be dispensed with at the outer end of the gutter extension usinginstead a bar 18 (see Figure 1) similar to bar 13. Blades 23 are at their inner ends pivoted on these bars or links by pins 24' as illustrated in the figures and in spaced relation. Links F and G must be provided for the part of the blade carrying means which passes into or over curve B. The blade carrying means therefore consists of bars 13, 18 and links F and G. I provide guiding means 19, preferably an angle iron with a downwardly extending lip 19 to hold the blade carrying means in operating position.

Member A as illustrated includes a motor 21 and a transmission 22 by which chain 15 is driven.

Curve E makes necessary the use of links F and G which are hinged together by pins 24, to certain of which blades 23 are hinged at their inner ends as at 24'. Pins 24 are also secured to bars 13 and 18 wherever blades are necessary.

Figs. 6 and 7 show details of the links F to which the scraper blades 23 are pivotally connected on the upright pins 24. The links are provided at one end with a single upstanding car 37 and at their opposite ends with spaced upstanding ears 38 which embrace the upstanding ear 37 of the next adjacent link. These parts are pivotally connected for articulation in a vertical plane by the pins 24 shown in Fig. 1.

Each link has an abutment 47 extending laterally from face 36 thereof and against which the scraper blade 23 stops on the forward stroke of the bar 13 to hold the blade transversely across the gutter. On the rearward stroke of the bar 13, the scraper blade merely pivots on the vertical axis of pin 24 to collapse toward the vertical face 36 of link F.

I will now further describe the design and operating characteristics of my invention. The transverse shape of may be dropped by gravity on an elevator which is promember C is shown in Figure 5 and it may be of any de-, sired length other than shown in Figure 1, this member being supported partially by post 20. The sides and bottom of members C and D register with the sides and bottom of member B, member B extending preferably through wall 25 of the building. Members C and D are preferably made from sheet steel and having flanges adapted to be securedtogether and to wall 25- as shown.

Member D is clearly illustrated in Figures 8 and 9, and the opening 26 of this member is considerably higher than opening 27 in wall 25. Opening 26 in member D is provided with a free closure 28 which is hinged to mem ber D as as 29-29. Member 28 will therefore be held normally closed by gravity, but will be free to swing outwardly on hinges 29 as axes.

In view of the inclined position of member C, material being moved will be inclined to slip back by gravity. I provide means which in its entirety is designated by reference character H to prevent this, comprising posts 30-30 which are secured to the side walls of member C and held together by plates having openings for the free reception of a shaft 32, the forward posts 30 being secured together preferably by an L iron 33. A number of fingers 34 are shaped as shown and welded to member 32 in spaced relation. Thus these members 34 at their free ends will drag over the material being forced upwardly and outwardly, thus to prevent the material from sliding back. L iron 33 is preferably positioned to hold the free ends of fingers 34 a short distance from the bottom 12' of member C.

I have only shown one of members H as a matter of convenience, others may be used depending upon the length of member C.

Having thus shown and described my invention, I claim:
